Context. The space mission Kepler provides us with long and uninterrupted photometric time series of red giants. We are now able to probe the rotational behaviour in their deep interiors using the observations of mixed modes. Aims. We aim to measure the rotational splittings in red giants and to derive scaling relations for rotation related to seismic and fundamental stellar parameters. Methods. We have developed a dedicated method for automated measurements of the rotational splittings in a… 

Rapidly rotating red giants

Stellar oscillations give seismic information on the internal properties of stars. Red giants are targets of interest since they present mixed modes, wich behave as pressure modes in the convective

Fast core rotation in red-giant stars as revealed by gravity-dominated mixed modes

An increasing rotation rate from the surface of the star to the stellar core in the interiors of red giants is reported using the rotational frequency splitting of recently detected ‘mixed modes’, which confirms the theoretical prediction of a steep gradient in the rotation profile towards the deep stellar interior.
